GPL-742 API endpoint in Lighthouse for creating Source Plate Events in the Events Warehouse

[andrewsparkes]

User story
When a source plate is scanned on the robot that has no barcode, no DART data or has no positives and will not be picked, we would like to write events for these barcodes so that reporting can use them. There should also be an event for when a source plate gets 'completed'. This API endpoint would need to be called from the Beckman method with a barcode (if available), event type and robot serial number at the relevant 4 points in the process.

Acceptance criteria
To be considered successful the solution must allow:

• Get the event warehouse working locally and improve documentation on how to do so/document why it cannot be used locally as a standalone application and what other dependencies need to be added to get a local, working instance
• Add RabbitMQ to lighthouse so we can write directly to queue (need equivalent of Warren in Ruby, write as module so easily reusable in other Python apps)
• Update deployment project with new configuration variables/files
• See confluence page below for the 4 types of event required. Handle all of these, sending messages with relevant events, subjects etc.
